  		Figure 2: Box plot of fluoroscopy time for venous access procedures. The horizontal line within the box is the median. The lower and upper ends of the box are the first and third quartiles. The height of the box is the interquartile range. The vertical lines extending above and below the box terminate on the data points furthest from the mean but within a distance of 1.5 times the interquartile range from the end of the box. Data points indicated by {circ} are outliers and are between one and a half to three times the interquartile range from the end of the box. Data points indicated by * are extremes and are more than three times the interquartile range from the end of the box.
